, My present invention relates to scoving,

and more particularly to an improved form pi portable scoving for brickkilns and the 5 As is well known, in a brick kiln it is necessary to'rotect the sides of the kiln by a scoving w ich. may be either builtonto the sides of the kiln or a portable scoving used, the idea being toeconomize fuel and obtain a more even heat during the burning process.What may be called permanent scoving is expensive to manufacture andresults in a great many" ruined brick} because of the material of thescoving adhering to the same during the burning process, Portablescoving'as at present utilized is also unsatisfactory because of thedifficulties of handling the same and the liability-to breakage a nwarping because of the intense heat to which it is subjected and nosatisfactory means has heretofore been devised for obviating the resultsof cracking or warping. Further, in portable scoving as at presentutilized, there is no satisfactory way of insertin thereln the usual andcommercial form of 'ln door. i In my present invention, I have obviatedthe objections to portable scoving as here- 1 ,tofore made and haveprovided a novel form of'port'able scoving which maybe easily andreadily handled by the ordinary conveyor mechanism found in af-brickkiln and in which any cracking due to expansion, contraction, orhandling of thematerial can be taken up. Further, in my new and improvedform of scoving the usual and c'o rnmercial type of kiln doors may-bebullt 1n and when so built in,"form a part of the scoving itself and maybe handledwlthsuch scoving. Also, by my improved mventionI am enabled tohold a section or sect ons of scoving in an upright 'pos1tion while thekiln is being emptied, and in 'a redetermined slope while the kilnisbeing lled and thereafter releasing the scoving so thatthe brick in,place and close up the space occasioned by the shrinking of the brlckduring the process of burning.-

In carrying out myimproved invention I arrange channel'irons 1 at thetop and bottom of the scoving which is built up from insulatin andfire-resisting material and arrange a pluralit of rods that runentirely" through the insu sting and fire-resisting ma -weight of thescoving will act to hold the te-rial' and such rods co-operate with thechannel irons at the top and bottom of the sections of scoving wherebythe rods, when placed under tension, will take up any cracking caused bythe expansion and conerly in theforks itwas necessary to have it so hungthatxthe slab was lying at an angle in the forks. This necessity forinclining the slab of scoving'rendered it impossible toaccuratelyposition the slab with respect to the kiln and also rendered necessary aconsiderable amount of room between the stacks of bricks and the postsof the kiln building. I have obviated this objection in my "presentstructure and have provided.

ineanssecured to the top of the slab of scovmg, such means being adaptedfor attachment to the crane hooks. I am enabled,'by

this improved structure, to manipulate the scoving. in the minimumamount of room which is of material advantage in allowing "the fullestuse of the kiln building'in building the kiln. By this method ofhandling the scoving I am also enabled to fix the slope of the scovingwith respect'to the yet unbuilt kiln, the s10 e given to the scovinggoverningthe settling of the brick inthe kiln, and after the kiln isbuilt, I utilize means associated with thescoving so that such scovingwill, follow the brick during the process of burning the same andprevent the openings which would otherwise occur.

The principal object of my invention, therefore, is an'improved andnovel form of portable scoving for brick kilns and the like.

Another object of my invention is a' portable scoving section'having asan integral part thereof and inset therein the commercial 1: pc of kilndoor.

cracking due to expansion and contraction or handling or warping of thescovin sec tion.

In the aaeompaayin drawingsilliistr'at beams 17.

ing a preferredembodiment of my'inve'ntion as located in a kiln,

Fig. 1 is a sectional elevation through a shedshowing'a kiln inelevation and with my improved scoving in position with respect to suchkiln, and

Fig. 2 is a side elevation of Fig. 1 's'howing in front elevation asection of scoving havi'ng jos'itioned 'as'an integral part there of thecommercial type of kiln.

Referring to the drawings, the shed is constructed in the usual 'mannerof a plurality of uprights 1Q spaced apart from each other and tiedtogether at their top by tie rods or beams 11, a roof 12 being built atthe upper end of the uprights 10. At any conv'enient'height above theground level and attached to the uprights 10 are supports 13 onthe'upper end of which rest and are secured eye "beams 14 runningparallel to the length of the shed as is usuah Secured to the top of'thebeams 14 are rails 15 arranged parallel to each other and constitutingtracks on which run wheels 16 rotatably. mounted on, and supporting, thetraveling crane Means are provided, as'indicated by the numeral 18, forcausing a rotary movement of the wheels 16 and'therefore a movement ofthe crane beams 17 along the length of the building while a travelingcarriage 19 is arranged with suitable means whereby an operator maycontrolthe crane mechanism. The above structure with regard to the craneis the usual structure and is well understood and a detailed descriptionthereof appears to be unnecessary. Between theground level andthesupporting'beams '13 and secured to the uprights 10 are beams 20provided at intervals with hooks 21 that extendinwardly towardtheinterior of the shed for a purpose to be hereinafter described.

As is usual, the kiln is built up of a plu-.

rality of stacks of bricks 22 arr'angedin' hacked relation in the usualmanner, the

kiln occupying the major portion of the floor space of the kiln, butleaving along each side wall, as defined by the posts 10, a passage forthe workmen. In place of the usual scoving I arrange sections ofportable scoving, said sections being constructed "by placing thechannel iron -23-'at.the bottom and a channel iron 24 at the toparranged (not shown) in the ch'a'nneli'r'on 24 and the extended ends ofsuch rods 26 are'threaded to receive nuts 27 and by means of which thechannel. irons 23 and'24 are forced firmly intoengagement with the topand bottom ends of the slab 25. As shown in Fig. 2, I have'arrangedthree rods 26 in the slab 25, but the number maybe varied as desired"without departing fro mthespirit of the invention. Secured to the topchannel mem ber are eyes 28 and the number of such eyes may 'be anynumber desired, though I have found "two tobe ample. Secured to each ofthe eyes 28 is one end of a chain 29, which chain may be attached to thehooks 21, above referred to, and whieh chain, as will be seen from aninspectiondf Fig. 1, prevents atoo far inward movement of the upperendof the s ec'tion of'scoving toward the kiln.

IVhere the section of scoving is to be "located around the kilnat apoint where it is,

desired to, fire the kiln','kiln doors 30 are arranged on the lo w'erchannel iron 23 and the slab of material 25 is molded around the same,thus securely fastening them in position.

In utilizing my improved sections of scoving, the kiln is built in theusual manner andfthe crane operatoiyby manipulating the crane, hooksonto the eyes 28 and transports the sections of scoving to any desiredposition around the kiln, as shown, for example,

in .the drawings, and, assuming it to be the ordinary section ofscoving, it isplaced with relation to the kiln with the channel iron 23closely adjacent to the bottom of the stack or unit 20 and inwardmovement of the upper endof the section of scoving 'is predetermined andlimited by the use of the chain 29 in connection with the books 21.

The kiln is nowbuilt up in the usual manner of'a, plurality of stacks orunits and,

when thekiln is completely built, it is entirely surrounded by thesections of scoving.

V The chains 29 may nowbe released from the hooks 21 so that the weightof the sections of scoving rests on the kiln and the tops of suchsections of scoving will move inward toward the center ofthe kiln as thebricks forming the stacks or units 22 shrink during theburningoperation. After the brick have been entirely burned, the tops of thesections of scoving maybe moved toward the line of posts 10 and heldthereagainst by meansof the chains 29 and hook 21 or may be moved toanyportion of the shed desired by the use of the traveling crane. 7

While I- have necessarily shown, and described the preferred embodimentof my invention somewhat in detail, it is to be under- I stood that Imay varyv the size, shape, and

arrangement of parts within wide limits without departing from thespirit of theinvention.

Having thus described my invention, what I claim as new is:

1. An improved portable scoving comprising a slab of insulating andfire-resisting material of suitable thickness and means for placing thematerial of the slab under compression. V

2. An improved portable scoving for brick kilns and the like comprisinga slab of insulating and fire-resisting material, a metallic memberarranged at each end thereof, tie rods extending through the slab ofmaterial and metallic members, and means associated with said tie rodsfor forcing the metallic members toward each other whereby the slab ofmaterial between such metallic membersis compressed and any cracksappearing in the slab from contraction and expansion or handling aretaken up.

i 3. An improved portable scoving comprising a. slab of insulating andfire-resisting material, channel irons arranged atthe top and'b'ottom ofsuch slab of material, a kiln door resting on the 'bottom'channel ironand fitting into and through the slab of insulating or fire-resistingmaterial, a plurality of tie rods extendin through the slab ofmateriaL'and means or placing said rods under tension whereby thechannel irons are forced toward each other to thereby compress thematerial of the slab to take up cracks in the material. 1 4. Thatimproved method of utilizing portable scovin in connection with thebuilding of kilns an the burning of the brick therein which consists insetting the portable scovmg at a predetermined slope to govern thesetting of the brick in the kiln, securing such scoving in suchpredetermined position during the building of the kiln and then releasmgthe scoving whereby such scoving will follow the brick during theprocess of burning to prevent openings in the kiln.

5. An improved portable scoving comprising'a slab of insulating andfire-resisting material of suitable thickness, means for. placing thematerial of the slab under compression, and operating rings secured tothe top edge of such slab.

6. An improved portable scoving for brick kilns and the like, comprisinga rectangular frame, bars extending longitudinally thereof, and a layerof fire-resisting material built into the rectangular frame andassociated with said bars. I

7 An improved portable scoving for brick kilns and the like, comprisinan open rectangular frame, a plurality o parallelly arranged rodssecured thereto, and a layer of fire-resisting and insulating materialbuilt into the open rectangular frame and sup.-

ported bythe parallelly arranged rods.

8. An lmproved portable scoving for brick kilns and the like comprisinga reinforcement and a layer of fire resisting material consisting of asingle integral slab.

In testimony whereof, I have signed my name to this specification. r
